Cohorting has to be helping.
Most cases in MIQ are picked up very early in their stay. Chances are after that that no more cases will be in that facility and can't cross transmit.
Agreed,
I also think the decision to then transfer positive cases to jet park in Auckland helps...
not sure how OZ does it, whether the group all their positives together, or allow them to remain in their original rooms..
